I-IUMIDIFYING APPARATUS.

Specification of Letters Patent.

Patented Jan. 9, 1,917.

Application filed October 25, 1916. Serial No. 127,512.

To all whom t may concern:

l Be it known that I, NICHOLAS J. YONKER, a citizen of the United States, residing at Holland, in the county of Ottawa and State of Michigan, have invented new and useful Improvements in Humidifying Apparatus, of which'the following is a specification.

The present invention relates to humidifying apparatus', and its object is generally to provide apparatus of that character which shall be simple and economical in construction; and more particularly, an apparatus of that character wherein the water which is being vaporized may be maintained at a desired level, and may be replenished Ifrom heated water under pressure; and further, to provide improved means forregulating the heating of the water. This, and

any other objects appearing hereinafter, are attained by, and the invention finds preferable embodiment in, the illustrative structure hereinafter described and illustrated by the accompanying drawings, in which Figure 1 is a sectional view of a humidifying apparatus taken on a vertical plane corresponding to line A-B of Fig. 2, and

showing a hot-'air furnace as the heater of such apparatus; Fig. 2 is a top plan vview of the same; Fig. 3 is a sectional view of the same taken on vertical planes corresponding to line C-D of Fig.v 2; Fig. 4 is a detail view of a 'float-operated valve, partly in axial section; and, Fig. 5 is a view of a screen for shutting oiil heat from the water containers of the humidifying apparatus.

In the embodiment of `the invention chosen for illustration by the drawings and for detailed description in the body of this specification, the apparatus is employed for humidifying air in dwellings and the like. An ordinary hot-air furnace 1, having the casing 2 and placed preferably in the base- Inent, for heating the air, is also utilized for evaporating the water for humidifying the air.

The apparatus is located within the airheating chamber formed by the casing, and comprises a closed water container 3, into which water is forced through a pipe 4 by suitable means, as from an elevated head or by the water pressure exerted by the pumping system from which .said pipe leads. Under such pressure, the water passes from the closed container into an open evaporating water container 5 through a suitable in` let 6 controlled by automatic means, as the float-operated valve 7 ofcommon form and having the ball fioat 8. It will be seen that when the water in the open container is exhausted by vaporization to a certain level, the valve automatically opens, and replenishing water passes into the open container, being forced thereinto by the pumping system or the water head pressing on the water in the closed container; a-nd that when the incoming water reaches the desired level, the valve closes. It will be seen also, that the water while in the closed container is being heated and thus prepared for ready vaporization, but by reason of being con-l fined under pressure, can not boil at the same temperature as that in the open container.` It Will be also seen that the water in the open or evaporating container is maintained at a certain level by the water heador pumping system as automatically controlled by the valve, and hence said con` tainer cannot become exhausted and dry. A suitable screen or shield 9 is movable into Aand out of positions between the heater and one or both of the containers, whereby the heat may be `to a greater or less degree shut ofi" from one or both containers, as may be desired. As shown, this screen is slidable in ways 10 and may be raised or lowered by a cord 11 attached thereto and passing over pulleys 12, 13. The `container 5 is shown provided with a corrugated inner wall 14 whereby the heating of the water therein is facilitated.

The invention being intended to be delined solely by the claims, is not to be limited to or by details of construction shown or described.

I claim:

1. In apparatus of the character described; a closed water container; means for forcing water thereinto; an open water container, having an inlet thereto whereby water may How from the closed to the open container; means for automatically controlling said flow; and a heater for heating the water in the containers and vaporizing.

in the containers and vaporizing the water in the open container.

3. In apparatus of the character described; a closed water container; means for forcing water thereinto; an open water container, having aninlet thereto whereby water may l'low from the closed to the open container; a float-operated valve in the open container for automatically controlling said flow a heater for heating the water in the containers and vaporizing the water in the open container; and a screen adapted to be moved into and out of position between the heater and said container.

4:. In apparatus of the character described; a closed water container; means for forcing water thereinto; an open water container, having an inlet thereto whereby Water may iiow from-the closed to the open container; a float-operatedvalve in the open container for automatically controlling said flow; a heater for heating the water in the containers and vaporizing the water in the lopen container; and a slidably mounted screen adapted to be slid into and out of position between the heater and said container.

5. In apparatus of the character described; a closed water container; means for forcing water thereinto; an open water container, having an inlet thereto whereby water may flow from the closed to the open container; means for automatically controlling said flow; a heater for heating the jwater in the containers and vaporizing the water in the open"container; and a casing for the containers and the heater.

6. In apparatus of the character described; a closed water container; means for forcing water thereinto; an open water container, having an inlet thereto whereby water may flow r om the closed to the open( container; a float-operated valve in the open container for automatically controlling said flow; a heater for heating the water in the containers and vaporizing the water in the open container; and a casing for the container and the heater.

7. In apparatus of the character described; a closed water container; means for forcing water thereinto; an open water container, having an inlet thereto whereby Water may iiow from the closed to the open container; a float-operated valve in the fopen container for automatically controlling said ow; a heater for heating the water in the containers and vaporizing the water in the open container; a screen adapted to be moved into and out of position between the heater and said container; and a casing for the container and theheater. 8. In apparatus of the character described; a closed water container; means for forcing Water thereinto; an open water container, having an inlet thereto whereby water may flow from the closed to the open container; a float-operated valve in the open container for automatically controlling said flow; a heater for heating the water in the containers and vaporizing the water in the open container; a slidably mounted screen adapted to be slid into and out of position between the heater and said container; and a casing, for the containers and the heater.

In testimony whereof have hereunto set my hand in presence of two subscribing witnesses, at Grand Rapids, Michigan, this 19th day of October A. D. 1916.
